By way of summation and review, examples of an organic optoelectric device may include an organic photoelectric device, an organic light emitting diode, an organic solar cell, and an organic photo-conductor drum, and the like. Among them, the organic light emitting diode (OLED) has recently drawn attention due to an increase in demand for flat panel displays. The organic light emitting diode converts electrical energy into light by applying current to an organic light emitting material, and has a structure in which an organic layer is interposed between an anode and a cathode. The organic layer may include an emission layer and an auxiliary layer, and the auxiliary layer may include at least one selected from, for example, a hole injection layer, a hole transport layer, an electron blocking layer, an electron transport layer, an electron injection layer, and a hole blocking layer, which may help improve efficiency and stability of an organic light emitting diode.

Performance of an organic light emitting diode may be affected by characteristics of the organic layer, and among them, may be mainly affected by characteristics of an organic material of the organic layer.

Increasing hole and electron mobility, and simultaneously increasing electrochemical stability of an organic material may be useful for application of the organic light emitting diode to a large-size flat panel display.

As described above, an embodiment provides a composition that may help realize an organic optoelectric device having high efficiency and long life-span. Efficiency and life-span may be improved due to bipolar characteristics of the hole transportable host and the electron transportable host.
